UNITED STATES PATENT OFFICE.

GEORGE A. KIT'IREDGE AND \VATSON P. KILBOURNE, OF CHICAGO, ILLINOIS.

UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 405,712, dated June 25,1889.

Application filed September 27, 1888. Serial No. 286,555. (No model.)

To all whom it may concern.-

Be it known that we, GEORGE A. KITTREDGE, a citizen of the UnitedStates, and WVATSON l3. KILBOURNE, a citizen of the Dominion of Canada,both residing at Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Umbrellas, of whichthe following is a specification.

Our invention consists of an improved umbrella, so constructed as to beeasily convertible into a walking-stick by removing the covering, ribs,and braces from the staff of the same, means being provided for holdingthe umbrella in an open position without catches or pins being used onthe staff.

Of the accompanying drawings, Figure 1 is a vertical transverse sectionof our improved umbrella, open. Fig. 2 is a view, partly in section, ofthe end ofthe umbrella-staff when converted into a cane. Fig. 3 is aview, partly in section, of the end of the umbrella when closed.

A is the stick or staff, made plane and smooth throughout its length andwithout the ordinary catches of pins usually found in umbrella-sticks.In the end of the stick A is permanently screwed the portion 0 of thesingle one-piece fastening-screw e e e, the central portion 6' of thesaid screw being preferably of larger diameter than the end portions 6e, for reasons presently to be plainly seen.

The ribs H of the umbrella-frame are pivoted in the usual manner to thehead E, the said head being centrally tapped to screw onto the enlargedportion 6'.

B is a ferrule closed at its outer end by the tip a and provided with aninterior screwthread, whereby it is screwed onto the threaded portion 6,the inner end of the ferrule accurately fitting against the uppersurfaceof the umbrella-head E. In the particular form herein shown the ferruleis provided with an interior plug 1), centrally tapped to screw onto theend 6 of the fastening-screw. The braces G are pivotally secured in theusual manner to the ribs II, and' at their inner ends are pivoted to therunner D. The upper portion of the runner forms a sleeve D, the lengthof which determines the highest position of the same on the stick, theparts being so arranged as to permit the said runner to be liftedslightly beyond the position required to spread the ribs and hold theumbrella wide open,thus enabling the braces to lock automatically whenthe umbrella is in this open position. The upward motion of the runnerin spreading the umbrella continues until the upper end of the sleeve Dbears against the under surface of the head E, at which position theinner ends of the braces G are slightly above the outer ends of thesame, as shown in Fig. 1, thereby causing the said braces toautomaticallylock and hold the umbrella in its extended position withoutthe aid of a spring-catch or pin of any kind in the umbrella-stick.

WVhen it is desired to convert the umbrella into a cane, the ferrule Bis first unscrewed from off the part c of the fastening-screw, and thehead E is unscrewed from oif the threaded portion 6', when the entireumbrellaframe secured to the head, consisting of the ribs, braces,runner, and covering F, is removed from the stick A. The ferrule B isthen screwed down onto the part c, as shown in Fig. 2, until the innerend of the said ferrule bears directly against the top of the stick A,forming a cane of neat and smooth appearance.

\Ve claim 1. In a combination cane-umbrella, a plane staff provided witha single one-piece fasten ing-screw at one end, in combination with anumbrella-head centrally tapped to enga e with said screw, and a ferruleprovided with an internal screw-thread, whereby the said ferrule may beheld on the said fasteningscrew either with or without the said head,substantially as described.

2. In an umbrella, a smooth staif provided at one end with a singleone-piece fasteningscrew having an enlarged threaded central portion 6',in combination with a head centrally tapped to engage with the part c,the umbrella-frame pivotally secured to said head, and a ferruleprovided with a screwthread, whereby the said ferrule may be held on thesaid fasteningscrew either with or without the umbrella-head,substantially as and for the purposes described.

In witness whereof we have-hereunto set our hands.
